The demand sensor wires are too close to the lights, so you wind up having to stop before it turns green. Also, if cars are coming from both directions, the demand system tends to get 180 degrees out of phase with the traffic and makes everyone stop.

A proper system is, well, like one on a self-driving car. Detect traffic from further back using the cameras rather than the sensor wires. Estimate the number of cars, speed, and position, then adjust for max flow.

Given the position/speed data that Google collects through Google play services (which assists then with determining traffic conditions for instance), I think Google could do much better at controlling the traffic lights (or at least provide one source of input for).
